Two cases of endometriosis causing ureteral stenosis are reported. Case 1. A 46-year-old woman was hospitalized with the complaint of right flank pain. Intravenous pyelography showed right hydronephrosis and retrograde pyelography revealed ureteral stenosis at the distal third ureter. Exploration revealed an abnormal periureteral mass, which was excised together with the distal part of the ureter. A right ureteroneocystostomy was performed with the Boari technique. Case 2. A 39-year-old woman was hospitalized with the complaint of pain in the left lower quadrant. A left retrograde pyelography showed stenosis of the ureter at 4 cm proximal of the bladder. An exploratory laparotomy revealed blue berry spots on the left side of the uterus and dense fibrous tissue around the ureter, which was successfully dissected out. The pathological diagnosis of both cases was extrinsic ureteral endometriosis. Ureteral endometriosis has rarely been described and the literatures on 30 cases reported in Japan were reviewed.

We report two successfully treated cases of ureteral endometriosis. Case 1 is in a 47-year-old female who had a past history of simple hysterectomy and right oophorectomy. Pathological diagnosis was myoma uteri and pelvic endometriosis. Two months later, she visited our clinic for right flank pain. Excretory urogram and retrograde pyelogram revealed right hydroureteronephrosis and stricture of the right lower ureter. The diagnosis of ureteral endometriosis was made from the past history and clinical features. Danazol therapy started with a daily dose of 400 mg. Sixteen days later, excretory urogram demonstrated complete resolution of the right hydronephrosis. An intravenous pyelography about 1 year after the danazol therapy has indicated no recurrence. Case 2 is in a 35-year-old female who visited our clinic for right lumbar pain. Excretory urogram and retrograde pyelogram revealed right hydroureteronephrosis and stricture of the right lower ureter. Right ureterocystoneostomy was performed unsuccessfully resulting in endoscopic dilation. Right lower ureter was buried in the dense fibrous tissue approximately 5 cm below the crossing with iliac vessels. The area of obstruction was removed. Histologically, endometriosis was diagnosed. Twenty nine cases of ureteral endometriosis including our two cases were collected from the Japanese literatures and reviewed with respect to the clinical features and treatment.

We present a case of ureteral endometriosis in a 48-year-old postmenopausal patient who was hospitalized complaining of right flank pain & microhematuria. She had no bladder irritability. She had a past history of simple hysterectomy and left oophorectomy because of adenomyomatosis. At that time, right ovary and other pelvic organs were normal. Physical examination revealed slight swelling of the liver without tenderness. Laboratory data at admission revealed severe liver dysfunction due to liver cirrhosis. Excretory urography demonstrated right hydronephroureterosis and severe stricture of the right lower ureter. Right ureteral catheterization demonstrated a high degree of stricture at the distal third. Cytology of right pelvic urine was negative. Right nephroureterectomy was done because long segment of right lower ureter adhered to the peritoneum tightly and we could not rule out ureteral cancer. Pathological diagnosis was extrinsic endometriosis of the right ureter. Ureteral endometriosis is rare and postmenopausal endometriosis is also rare. In our case hyperestrogenemia caused by liver cirrhosis might have played a role in the genesis and progression of endometriosis.

We treated 17 patients with severe endometriosis involving the genitourinary tract. Eight women presented with persistent right or left flank pain, two presented with known ureteral obstruction, and five presented with urinary frequency and burning, and/or hematuria with their periods. Presented are the results of laparoscopic management in these patients. We performed segmental bladder resection in six patients and ureteral resection and reanastomosis in two. Nine additional patients underwent partial resection of the ureteral wall for complete removal of endometrial implants. The ureter was repaired with 4-0 PDS in seven patients and a stent was left in place for 4 to 6 weeks. Two required only a stent due to the small size of the ureterotomy. The postoperative course of these patients was uneventful. Following ureteral repair/reanastomosis, all women underwent an intravenous pyelogram at follow-up, and normal bilateral excretion was demonstrated. Cystoscopy revealed no abnormal findings in five patients who had undergone partial bladder resection. All patients reported significant pain relief or complete resolution of symptoms. Operative laparoscopy can be safely used to achieve relief from severe symptomatic endometriosis of the genitourinary tract.

A 48-year-old female was found to have right flank pain at another hospital and transabdominal ultrasonography showed right hydronephrosis. She was referred to our department for further examination. She had undergone right oophorectomy and total hysterectomy 3 years before. Intravenous pyelography showed right hydronephrosis and retrograde pyelography revealed ureteral stenosis at the lower portion of the right ureter. Endometriosis had developed at the site of previous surgery on the appendix. A mass was formed in an extensive area including the endometriotic lesion, due to adhesion following previous surgery or other reasons, and extended to the retroperitoneum, thereby inducing right ureteral stenosis. The postoperative course was uneventful. The pathological diagnosis was endometriosis of the residual appendix.

We report 8 cases of ureteral endometriosis. The mean age of the 8 patients was 42 years (range 29 to 60). In all patients, endometrial lesions were located in the lower third of the ureter and were unilateral. Six patients presented with flank pain and in one of the 6 cases the pain was associated with menses. One presented with gross hematuria. One had no symptoms. Seven out of 8 cases had gynecological diseases and 4 had had surgical treatment for the gynecological diseases. Four patients were treated with gonadotropin-releasing hormone (Gn-RH) analogue for hydronephrosis of endometriosis. In 2 patients, the therapy was effective, but hydronephrosis recurred. Surgical therapy was done on all patients. We recommend surgical therapy for hydronephrosis with ureteral endometriosis.

A 32 year old lady presented with recurrent left flank pain for 4 weeks and chronic lower back pain. CT without contrast showed no stones and mild left hydronephrosis. CT of the spine suggested an inflammatory process at L5-S1 vertebra. The diagnosis was supported by a bone scan. Incidentally, the scan showed nonfunctioning left kidney. Diuretic renography confirmed poor perfusion and no excretion. A retrograde study showed narrowing of the ureter at the pelvic brim. Ureteroscopy showed a papillary mass in the lumen of the ureter from which multiple cold cup biopsies were taken. The pathology however was not conclusive. A robotic nephroureterectomy was carried out. Definitive pathology showed intrinsic endometriosis of the ureter. We conclude that endometriosis should be considered in the differential diagnosis of unexplained ureteric obstruction and ureteric lumen filling defects in young women.

Endometriosis is a common gynecological condition, but involvement of the urinary tract is rare. Ureteral endometriosis can present in a nonspecific fashion, and may mimic ureteral malignancy. This case report describes a 44-year-old woman who initially presented with chronic flank pain and was found to have left-sided renal dysfunction and a distal left ureteric mass. She was eventually diagnosed with ureteral endometriosis after undergoing nephroureterectomy for what was thought to be either a ureteral fibroepithelial polyp or transitional cell carcinoma. Ureteral endometriosis should be considered in the differential diagnosis for a woman presenting with obstructive uropathy in the presence of a ureteric mass.

A 41-year-old female patient presented with left-sided flank pain and gross hematuria temporally unrelated to her menstrual cycle. Abdominal computed tomography scan showed a large left-sided solid, enhancing kidney mass radiographically consistent with renal cell carcinoma. Following surgical resection, histopathological examination revealed polypoid endometriosis. Polypoid endometriosis is rare and mimics a neoplasm clinically, radiographically, and on gross examination. Patients with polypoid endometriosis often present with symptoms related to mass effect rather than classic endometriosis hallmark symptoms such as dyspareunia, dysmenorrhea, and cyclic abdominal pain. Treatment includes surgical resection.

Background: Endometriosis is a multifactorial benign disorder characterized by the abnormal presence of endometrial tissue in an extraendometrial site. Although extrapelvic endometriosis is uncommon, symptomatic involvement of the kidney is exceedingly rare. This benign disease can mimic several urologic processes, but because of its scarcity in clinical practice, it is seldom considered in the differential. Case Presentation: In this report, we describe the case of a 45-year-old woman with flank pain and hematuria, who was found to have a left renal mass on cross-sectional imaging. After robotic partial nephrectomy, pathologic analysis revealed an endometrial implant within the renal parenchyma. Conclusion: This case of renal endometriosis highlights how this benign disease process can mimic several more sinister urologic processes.
